With two noted defensive programs squaring off, Monday night’s game was supposed to be one of those low-scoring, grind-it-out affairs.

An NBA game broke out at the Civic Center instead.

Florida State shot 68 percent from the floor en route to a 101-90 win over Georgetown in the second round of the NIT.

FSU (21-13) advances to play Louisiana Tech on Wednesday at home in the quarterfinals of the tournament, with the winner advancing to the semifinals in Madison Square Garden.

“It was a lot of fun,” said sophomore Aaron Thomas, who tied a career high with 26 points. “To see shots fall and shoot a real good percentage like that, it just goes to show we’re capable if we focus.”

Florida State hit 30 of 44 shots from the field, 11 of 16 from 3-point range and 30 of 38 from the free-throw line.

Sophomore guard Devon Bookert had his best game in an FSU uniform, setting a career high with 21 points and tying another with nine assists.

He also added two steals and five rebounds for the Seminoles, who scored 100 points for the second time this season — they put up 106 against Charlotte earlier in the year.

It was the first time in 13 years Georgetown allowed more than 100 in a regulation game.

“Wow,” Thomas said. “I didn’t know that.”

Florida State senior Ian Miller, hobbled by a lingering foot injury, came off the bench to score 18 points for the Seminoles and fellow senior Okaro White added 16. Every scholarship player available hit at least one basket.

“We haven’t had very many games where everybody is playing well at the same time,” FSU head coach Leonard Hamilton said.

And none were more important than Bookert, who knocked down every open jumper he had in the first half and was 10 of 12 from the free-throw line.

“I just think it’s letting the game come to me, I guess,” the sophomore guard said of his career night. “Like shooting easier shots, not rushing them. Just in the flow of the game.”

Said Thomas of his teammate: “Like Coach Ham says, he brought his big-boy pants today. He was aggressive. … He was more confident.”

As well as Florida State shot for the entire night, it was still a game late in the first half. The Seminoles led 36-33 when FSU’s Boris Bojanovsky and Georgetown’s Bradley Hayes were issued double technical fouls.

Then Miller hit back-to-back 3-pointers and freshman Jarquez Smith followed with a dunk on an alley-oop from Bookert.

On Florida State’s next possession, Thomas hit a 3-pointer from the top of the key while being fouled and the Seminoles went into the break up 48-35.

“I think it gave us a lot of momentum, especially going into the half,” Bookert said of the lightning quick 12-2 run. “It gave us that little extra boost.”

Florida State was 8 of 13 from 3-point range in the first half and 3 of 3 in the second.

“They were making 3’s no matter what defense we threw at them,” Georgetown head coach John Thompson III said.

His Hoyas (18-15) never got closer than eight in the second half. Not because Florida State’s rarely used zone defense was suffocating. The Hoyas did score 55 after halftime and starting guards D’Vauntes Smith-Rivera (22 points) and Markel Starks (27) combined for 49 points overall.

“We have not played very much zone,” Hamilton said with a smile. “And if you (look) back to the second half you see why. But we thought we had to change our defensive philosophy because Georgetown does a great job of executing their Princeton offense.”

In reality, it didn’t end up mattering how well Florida State played defense, because the Seminoles simply couldn’t be stopped on the other end. They shot 74 percent in the second half and hit 22 of 27 free throws.

Hamilton said he wasn’t sure Miller would play on Monday night until right before the game. Good thing, as the senior guard scored 12 points in the second half before leaving the floor with 1:24 left after picking up a technical foul.

“I didn’t know until right before the game started,” Hamilton said. “He said, ‘I feel pretty good.’ He hadn’t had any reps on defense at all. Matter of fact, he hadn’t any reps on offense or defense. He’s been a little sore, but it started improving toward the middle of the week.
